摘　　要：利用矩阵传递法推算了FWD动荷载作用下沥青路面层状弹性体系单层模量的反算公式,并编制了计算程序来反算单层的模量,可用于分析和评估路面单层的承载能力.利用计算程序,对某工程项目的基层测得的FWD弯沉数据进行了反算,与材料的室内试验数据进行比较,结果显示反算数据与试验数据基本吻合,验证了反算模型的可用性.Utilizing the methods of transfer matrix,the monolayer modulus back-calculation formula on the multilayered elastic body of asphalt pavement under the action of FWD dynamic load was derived,and the compute program was writed,which can be used to analyze and evaluate the bearing capacity of the monolayer pavement structure.The data of base course of FWD in the certain engineering was back-calculated by means of this program.Compared with the test results indoors,the back-calculation results were nearly the same.This indicates that the back-calculation model is reliable.
